Cable and Wireless Network Interfaces
Frequency Mapping
The Hub receives a digitally modulated RF signal in the range between 90 and 860 MHz to and
up converts it to one of the six available wireless carriers in the range 5.8 GHz license-free
band. The channel can be 64 QAM or 256 QAM and up to 6 MHz wide.
The CPE receives the wireless signal and down converts it to an RF channel in the range 90 to
150 MHz which is provided to a Cable Modem.
The CPE receives a digitally modulated RF signal in the range between 5 to 42 MHz and up
converts it to a fixed frequency in the range 5.8 GHz license free band.
The Hub receives the wireless signal and down converts it to the appropriate RF channel in the
range 5 to 42 MHz.
Signal Levels
The Hub includes Automatic Gain Control (AGC) on the RF input and can accept an RF input
signal of 0 to +30 dBmV while providing optimum wireless transmit power. The hub wireless
transmitter power, determined by the Downstream Transmit Power setting, can be set for on
of three modes: High, Medium or Test mode.
Note: The “High” power setting is for use with the AX1455-SM-Network Hub. Use of the “High”
power setting with the AX1455-SM-25 cancels the FCC certification and voids the user’s
authority to operate the unit in the 5.8 GHz band.
The upstream output power out of the Hub into the cable plant is controlled by the Upstream
Attenuation parameter. This parameter is automatically set by the Hub based on the transmit
power setting of the Embedded Cable Modem (ECM) contained in the Hub.
